<p class=MsoNormal>Hi. I am having a problem
whilst carrying out some preliminary testing of DRBD with OpenAIS. My
test setup was all working fine. I have now introduced it to a simulated wide
area network by changing the subnet on each system, modifying the config files
accordingly, adding the relevant routes and gateway, and using an established
Linux box that we use for throttling bandwidth for such testing. The network
config is sound as I can ping to and from each node through the router system.
I also have full key authentication setup between them. Nothing else has
changed.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Now, the DRBD nodes are failing to sync. I am getting no obvious
errors. If I watch the /proc/drbd file, it goes through the motion of syncing, and
the progress bar briefly is seen. It then flips back.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Below is a typical output of cat /proc/drbd ran one after
the other. It just goes on and on like this, and never actually syncs. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any ideas? I have pasted the relevant parts of my
config files further below.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks<o:p></o:p></p>
